The Max Planck In­sti­tute for Mar­ine Mi­cro­bi­o­logy (MPIMM) was foun­ded in 1992 in the State of Bre­men and is part of the cam­pus of the Uni­versity of Bre­men. It be­longs to the Bio­logy & Med­ical Sec­tion of the Max Planck So­ci­ety. The main fo­cus of our re­search is on the di­versity and func­tions of mar­ine mi­croor­gan­isms and their in­ter­ac­tions with the mar­ine en­vir­on­ment. Start­ing from the be­gin­ning on re­search­ers at the MPIMM took part in in­ter­na­tional ex­ped­i­tions world­wide. They are in­ter­na­tion­ally re­cog­nized for their ex­pert­ise in mar­ine mi­cro­bi­o­logy and for the ana­lysis of pro­cesses. These strong suc­cess­ful ef­forts are re­war­ded by many pub­lic­a­tions in top sci­entific journ­als.
